Questions & Answers about Njegova plava košulja je čista.
Because the possessive adjective njegova has to agree with the noun košulja in gender, number, and case.
- košulja = feminine, singular, nominative (it’s the subject)
- So njegov (“his”) must take the feminine singular nominative form: njegova
Basic nominative forms of njegov (“his”) are:
- Masculine noun: njegov (e.g. njegov kaput – his coat)
- Feminine noun: njegova (e.g. njegova košulja)
- Neuter noun: njegovo (e.g. njegovo dijete – his child)
Both njegova and plava are adjectives (one is possessive, one is descriptive) that modify the same noun košulja, so they must all agree with that noun:
- košulja = feminine, singular, nominative
- So:
- njegov → njegova (fem. sg. nom.)
- plav → plava (fem. sg. nom.)
This is called adjective agreement: all adjectives in a noun phrase match the noun’s gender, number, and case.
